  • "I pushed to work with you guys to show
    FSA/HSA eligibility only to US-based
    customers. With other solutions, it was
    falling on me and it was a bit of a
    nightmare implementation-wise."
  • "This is super plug and play.
    We're so happy people can use their
    FSA/HSA dollars on our products now.
    Anything like this that doesn't add
    friction for users, but expand how they
    can pay for our products is just great."
  • "We're thrilled with the performance
    so far! So glad this works with
    subscriptions by default too."

FAQs

FAQs

Do we need to change our checkout or add a new payment method?
No. Burst works post-purchase. Customers check out exactly as they do today using their preferred payment method. Burst is the only platform that supports FSA and HSA reimbursement while preserving express checkout options like Shop Pay, Apple Pay, Google Pay, and more.
How does Burst affect our existing payments and payouts?
It doesn’t. You continue to get paid through your current payment processor such as Shopify Payments or Stripe. Burst never touches your funds or delays payout.
How do customers know an item is FSA/HSA eligible?
Burst surfaces eligibility through on-site badges, messaging, and post-purchase confirmation. Customers see that reimbursement is available without needing to use a benefit card at checkout.
What products are eligible for reimbursement?
Burst supports all IRS-eligible health and wellness products under IRS Section 213(d). Eligibility is handled at the SKU level, and Burst issues Letters of Medical Necessity automatically when required.
How are subscriptions handled?
Burst is the only platform that automatically files FSA and HSA reimbursements for subscription purchases. Once eligibility is established, claims are submitted each billing cycle with no re-approval or manual steps required from the customer.

Yes. Burst supports telehealth visits, digital care programs, subscriptions, and services, including recurring care models that require ongoing reimbursement.

Yes. Burst supports in-store purchases, allowing customers to get reimbursed even when they pay in person.
Which TPAs does Burst work with?
Burst submits claims to all major third-party administrators, including HealthEquity, Optum, Fidelity, HSA Bank, and others.
What’s required from our team to stay compliant?
Nothing beyond installation. Burst handles eligibility logic, Letters of Medical Necessity, documentation, and claims submission. Your team does not need to manage compliance workflows or benefit rules.
Is Burst SOC II compliant?
